Any recommendation for a Speed & Feed App for smartphone/tablet ?

Learn to do the math.

I can do the math, remembering the cutting speeds for different materials is another.
Just started re-learning metalworking so not something I do all the time.
Since I don't have a chart I can post in my shop, figured an App would be the next best thing.

You can always print out that chart, then sketch up a table for your mill. Something like "1/2" endmill: Mild steel = 800 RPM"

So you can always look up in seconds what speed you need, no charts, math, or confusion. Since my mill only has one usable speed, I don't worry about it too much LOL :p :)
 
Speed and feed are both very wiggly concepts regardless of available equipment, do what works for you and your machine with the material you are milling/turning. Size matters a good deal, turning a part on a lathe that is 1" out of the spindle is considerably different then a part that is held in a steady rest 20" out.
I have the luxury of using my employers tools, I do however have time constraints for each job. I begin at what I think the tooling/part can handle from past expeirence and run it hard, if I get a poor finish or rapid tool failure then I begin to slow it down. When I owned my own shop (20 years) I worked in the opposite direction, start slow and then get faster.

To sum up, there are untold numbers of speed and feed charts/formulas/misinformation/old wives tales/outright BS, do what works on your machine, over time you will know what will work and what will not work. At this point you will have become "a machinist" (-:

Maybe someday, but until then I'd like to not ruin a bunch of end mills.
Trial and error hasn't worked too bad on the lathe, but I've broken a couple end mills.
Mostly wanted it for the mill, bit of a pain changing the belt around changing speeds.
 
FSwiz was way too aggresive for me. That's high end stuff F&S I was told. Made sense too after I pulled down GWizard I had much better results. But I do agree w/ knowing he formulas to a point. Then I can move around the IPT chip load values and experiment w/ knowing some basics about what will happen. And enjoy of course.
 
Jpigg, go here and download the sheets you need for the materials you commonly work with: http://www.niagaracutter.com/techinfo/common_mat/index.html

They will give you the info you need for both slotting and edge work. As WreckWreck says, these are starting points but they are very good starting points. Apps are fine but the info in the Niagara charts allows you to decide how much of the cutter is engaged, something an App may not give you.
